pub fn order_by<S: RankingStrategy + ?Sized>(
strategy: &S,
frames: Vec<(String, ContextFrame)>,
) -> Vec<(String, ContextFrame)>Expand description
Rank frames with a host’s ranking::RankingStrategy, then place the
ranking at the attention-favored edges with fold_to_edges — the general
form of order_by_value, which is this with
ranking::ScoreDescending.
Placement and ranking are separable and stay separated: every strategy yields a best-first total order, and the fold is the same either way.
